BIO 1301 Comprehensive Final Exam Notes |
Biology Made Easy
In glycolysis, glucose is converted to
pyruvate
The NET result of two molecules of glucose undergoing glycolysis is the formation of
4 NADH and 4 ATP
In muscle cells deprived of oxygen, the end product of glycolysis is converted to
lactic acid
During an intermediate step of the pathway called ______, a 6-carbon sugar diphosphate
molecule is split into two, 3-carbon sugar phosphate molecules.
glycolysis
Before entering the Krebs cycle, pyruvate is converted to
acetyl CoA
Three "turns" of the Krebs cycle will yield
3 ATP, 9 NADH, and 3 FADH2
The electrons that are transferred through the electron transport system are brought there by
NADH and FADH2
When ______ accepts electrons at the end of the electron transport chain, ______ is produced
as a by-product
oxygen; water
How do the products of glycolysis and the Krebs cycle relate to the electron transport chain?
Glycolysis and the Krebs cycle produce the molecules that shuttle electrons to the electron
transport chain
What key role does cellular respiration play in cells?
It generates ATP, which cells can use to do work
What is the theoretical yield of ATP from cellular respiration of 2,000 glucose molecules?
, 72,000
Match each compound with the step of cellular respiration that produces it. Some answers may
be used more than once. Some may not be used at all.
Glycolysis- ATP; Pyruvate; NADH
Krebs cycle- NADH; FADH2; ATP; CO2
Electron transport chain- ATP; H2O
When carbon atoms are removed from organic molecules during the transition step and the
Krebs cycle, the carbon atoms are released as
carbon dioxide
Use the DNA template strand below to simulate transcription of an RNA strand. Type the
complementary RNA strand in the box.
Template strand: A A T A C G G C C
UUAUGCCGG
What is removed during mRNA processing?
introns
A mutation in a gene would cause a change in the sequence of amino acids in a protein.
sometimes
What acts as a connector to help convert the nucleotide sequence of mRNA into the amino acid
sequence of a polypeptide during translation?
tRNA
mRNA is to translation as DNA is to
transcription
What is wrong with the following piece of mRNA? TACCAGGATCACTTTGCCA
It contains T and not U
Choose the option below that contains the correct complementary DNA sequence to the
following: 5' - AAGTCATTGCCGTA - 3'
3' - TTCAGTAACGGCAT - 5'
Match each structure or molecule found in chloroplasts with its correct label
